Abstract

The invention discloses a heat recovery method for automobile high-strength steel sheet stamping, which relates to the field of hot stamping and forming processing. A stamping mold is hollow inside; the inner part of the stamping mold is communicated with the inner part of a heating furnace through a high temperature resistant pipeline; the stamping mold is preheated and insulated through flue gas of the heating furnace. The stamping mold provided by the embodiment is directly heated by the flue gas produced by the heating furnace, the heating furnace can continuously provide a heat source, and no extra heating device is required to be arranged, so that the space is saved, meanwhile, the heat produced by the heating furnace is fully utilized, and the problem of high energy consumption in the prior art is solved.

Description

A kind of heat recovery method of high Strength Steel for Motor Vehicles punching press
Technical field
The present invention relates to hot press-formed manufacture field, more particularly to a kind of high Strength Steel for Motor Vehicles punching press Heat recovery method.
Background technology
For adapting to automotive light weight technology, reducing fuel consumption, reduce pollutant emission and improve wanting of Crash Safety Design of Vehicles Ask, the use proportion of high Strength Steel for Motor Vehicles is increasing.
Current Ge great automobile factory produces vehicle body and part mainly adopts cold stamping, using this method punching press pattern material with high strength When, the stamping press needing in punching course is big and easily ftractures, and produces excessive resilience.(anti-in particular for ultrahigh-strength steel plates Tensile strength >=550mpa), during punching press, this two defects are especially prominent.Drop stamping technology can solve this two problems, may be used simultaneously So that the finished product tensile strength after punching press is greatly improved.
The critical process process of drop stamping is heating, punching press, pressurize and cooling.Heating process directly influences high strength steel The punching performance of plate.The capital equipment of drop stamping includes: heating furnace, handling equipment, press, mould, trimming and punching are empty.Using After drop stamping technique, the thickness of especially high intensity used by coachbuilt body or ultrahigh-strength steel plates can reduce, simultaneously because portion The intensity of part is greatly improved, and the reinforcing plate on vehicle body, reinforcement can reduce in a large number, thus decreasing the weight of vehicle body Amount, improves the Collsion proof safety of vehicle body under equal conditions.Due to adopting heat processing technique, the heat deformability of steel plate obtains greatly Width improves, and the pressure relative reduction needed for Pressing Deformation is it is however generally that the tonnage 800t of drop stamping milling train just can meet Production requirement.Punching press in hot state, also reduces the degree of resilience, does not substantially have resilience.
Relatively for cold stamping, drop stamping also has weak point.Due to needing heating furnace to carry out pre-treatment to steel plate, increase Firing equipment and its this big link of energy consumption.
Content of the invention
The present invention provides a kind of heat recovery method of high Strength Steel for Motor Vehicles punching press, to solve prior art high energy consumption Problem.
For solving above-mentioned technical problem, the present invention employs the following technical solutions:
A kind of heat recovery method of high Strength Steel for Motor Vehicles punching press, the flue gas preheating of the heated stove of diel, Insulation.
More excellent, it is set to hollow inside described diel, diel is internal to pass through high-temperature resistant tube with inside heating furnace Road is connected.
More excellent, the inside of described diel is also connected with cooling water pipeline, described cooling water pipeline and high-temperature resistant pipeline On be equipped with control valve.
More excellent, the water vapour being formed after described cooling water heat exchange drives steam-driven generator to generate electricity.
Compared with prior art, diel of the present invention is directly heated by the flue gas that heating furnace produces, and need not additionally set Put unnecessary heater, the space-saving heat simultaneously also taking full advantage of heating furnace generation, thus solve existing skill The problem of art high energy consumption.
Specific embodiment
The application principle of the present invention, effect and effect, are explained by mode is implemented as follows.
Embodiment 1
A kind of heat recovery method of high Strength Steel for Motor Vehicles punching press, will be set to hollow, stamping die inside diel Tool is internal to be connected by high-temperature resistant pipeline with inside heating furnace, the flue gas preheating of the heated stove of diel, insulation.
The diel of the present embodiment is directly heated by the flue gas that heating furnace produces, and heating furnace can persistently provide heat Source, need not additionally arrange unnecessary heater, the space-saving heat simultaneously also taking full advantage of heating furnace generation, thus Solve the problems, such as prior art high energy consumption.
Embodiment 2
Excellent further on the basis of the heat recovery method of a kind of high Strength Steel for Motor Vehicles punching press described in embodiment Change, the inside of described diel is also connected with cooling water pipeline, described cooling water pipeline and high-temperature resistant pipeline are equipped with control Valve, the water vapour being formed after described cooling water heat exchange drives steam-driven generator to generate electricity, further with the waste heat that device is last.
It is embodiments of the invention as mentioned above.The present invention is not limited to above-mentioned embodiment, and anyone should learn The structure change made under the enlightenment of the present invention, every have same or like technical scheme with the present invention, each falls within this Within the protection domain of invention.
